Method and device for preventing and controlling cross infection of detected crowds at nucleic acid detection sampling points

Abstract

The invention provides a method and device for preventing and controlling cross infection of detected crowds at nucleic acid detection sampling points. The technical concept of the invention is as follows: gas exhaled by an examinee is sucked, and then filtered by a filter membrane, so that pathogens are attached to the surface of the filter membrane or in membrane holes, then the filter membrane is circulated and enters a disinfection cavity, the pathogens are inactivated by a disinfection device, and the filter membrane is reused; a sensor assembly is used for spacing isolation cloth to position the forehead of the examinee and collecting information such as body temperature and head portrait of the examinee, when the examinee leaves, the isolation cloth and the filter membrane move into the disinfection cavity to be disinfected, and the isolation cloth is located between the sensor assembly and the examinee, so that contact infection is avoided; and when the examinee is sampled through a wind shield and a swing sealing plate, the gap between the isolation cloth and the filter membrane entering and exiting the disinfection cavity is reduced, the air tightness of the disinfection cavity is improved, the problems that disinfection equipment is large in size and high in disinfection energy consumption due to the fact that gas exhaled by the examinee is completely disinfected are solved, and the device has the advantages of being good in disinfection effect and high in sampling efficiency.

Description

technical field [0001] The invention belongs to the field of environmental sanitation, and in particular relates to a nucleic acid detection sampling point cross-infection prevention and control method and device for tested populations in the technical field of respiratory nucleic acid detection equipment. Background technique [0002] During the pneumonia epidemic, identifying and isolating pneumonia patients as early as possible is the key to controlling the epidemic, and nucleic acid testing is the diagnostic standard for the disease. Pharyngeal swab nucleic acid specimen collection, as one of the important screening methods, has the advantage of simplicity and ease. When conducting nucleic acid testing and sampling for all residents, community workers and volunteers are responsible for inputting the information of the pre-collectors, guiding the personnel into groups, arranging sampling in different periods, and setting up the venue in the early stage. standards and nor...

Problems solved by technology

[0004] In order to solve the problem that the gas exhaled by the previous subject is cross-infected to the subsequent medical staff and subsequent subjects when collecting "nose test" or "pharynx test" samples in the nucleic acid detection process, the present invention provides a nucleic acid The cross-infection prevention and control method and device of the tested population at the detection sampling point, the technical concept of the present invention is to filter the exhaled gas of the subject through the filter membrane through suction, so that the pathogens are attached to the surface of the filter membrane or in the membrane pores, and then let the filter Membrane cycle turnover, using the disinfection device to inactivate pathogens at the same time as the turnover, and the filter membrane is reused, which solves the problem of directly disinfecting the exhaled gas of the subject. The volume of the gas to be sterilized is large and the energy consumption is high. The exhaled gas to be sterilized is changed to a sterilized filter membrane, which greatly reduces the volume and number of sterilized objects. The filter membrane can rotate slowly, and there is no need to purify the filtered gas when sterilizing the filter membrane. It is safe and reliable, and does not need to store the filtered gas. The disinfection device required to sterilize the filter membrane is simple, and only needs ultraviolet radiation or formaldehyde soaking or high-temperature disinfection.
